.TH std::get_money 3 "2024.06.10" "http://cppreference.com" "C++ Standard Libary"
.SH NAME
std::get_money \- std::get_money

.SH Synopsis
   Defined in header <iomanip>
   template< class MoneyT >                                      \fI(since C++11)\fP
   /*unspecified*/ get_money( MoneyT& mon, bool intl = false );

   When used in an expression in >> get_money(mon, intl), parses the character input as
   a monetary value, as specified by the std::money_get facet of the locale currently
   imbued in in, and stores the value in mon.

   The extraction operation in in >> get_money(mon, intl) behaves as a
   FormattedInputFunction.

.SH Parameters

   mon  - variable where monetary value will be written. Can be either long double or
          std::basic_string
   intl - expects to find required international currency strings if true, expects
          optional currency symbols otherwise

.SH Return value

   An object of unspecified type such that

     * if in is an object of type std::basic_istream<CharT, Traits>, the expression in
       >> get_money(mon, intl)
          * has type std::basic_istream<CharT, Traits>&
          * has value in
          * behaves as if it called f(in, mon, intl)

   where the function f is defined as:

 template<class CharT, class Traits, class MoneyT>
 void f(std::basic_ios<CharT, Traits>& str, MoneyT& mon, bool intl)
 {
     using Iter = std::istreambuf_iterator<CharT, Traits>;
     using MoneyGet = std::money_get<CharT, Iter>;

     std::ios_base::iostate err = std::ios_base::goodbit;
     const MoneyGet& mg = std::use_facet<MoneyGet>(str.getloc());

     mg.get(Iter(str.rdbuf()), Iter(), intl, str, err, mon);

     if (err != std::ios_base::goodbit)
         str.setstate(err);
 }

.SH Example


// Run this code

 #include <iomanip>
 #include <iostream>
 #include <locale>
 #include <sstream>

 int main()
 {
     std::istringstream in("$1,234.56 2.22 USD  3.33");
     long double v1, v2;
     std::string v3;

     in.imbue(std::locale("en_US.UTF-8"));
     in >> std::get_money(v1) >> std::get_money(v2) >> std::get_money(v3, true);

     if (in)
         std::cout << std::quoted(in.str()) << " parsed as: "
                   << v1 << ", " << v2 << ", " << v3 << '\\n';
     else
         std::cout << "Parse failed";
 }

.SH Output:

 "$1,234.56 2.22 USD  3.33" parsed as: 123456, 222, 333
